结构白是自然界最迷人的现象之一，在体温调节和交配中起着重要的作用。然而，引起可见光宽带反射的结构通常是准有序分布，这阻碍了对其颜色形成机制的系统研究。在这里，通过数值分析，morpho这些尺度的结构分布在管状和陀螺结构之间的各种管状形态。然后，利用周期数值框架与随机单元相结合建立的数值模型，讨论了结构白化的机理。热力学实验表明，在直射光束下，白色鳞片可以有效地降低蝴蝶翅膀的温度。我们的工作为分析准有序结构提供了一种简明的方法。该数值模型开发的方法可以促进对这些结构特征所促进的性能改进的深入理解。相应的解决方案可以指导纳米光学材料的设计，实现高效的冷却、伪装和光热转换系统。
As one of the most fascinating phenomena, structural whiteness in natural organisms serves important functions in thermoregulation and mating. However, the architectures that cause visible broadband reflection are often in quasiordered distributions, which hinders systematic research on their color formation mechanisms. Here, through numerical analysis, the architectures inMorpho theseusscales are shown to be distributed in various tubular morphologies between tubular and gyroid structures. Then, the mechanism of structural white is discussed using the numerical model built with the combination of a periodic numerical framework and random elements. Thermodynamic experiments indicate that the white scales can efficiently help reduce the temperature of butterfly wings under a direct light beam. Our work provides a concise method for analyzing quasiordered structures. The methodology developed by this numerical model can facilitate a deep understanding of the performance improvement facilitated by these structural characteristics. Corresponding solutions can guide the design of nano-optical materials to achieve an efficient cooling, camouflage, and photothermal conversion system.
